Abstract

The study on the effect of the organic fertilizers on the productivity of the two tomato varieties has been achieved in the municipality of Parakou in the northern Benin. The objective of this study is to evaluate the effect of the cow, chicken and goat dungs on the growth and fruit yield of two varieties of tomato (F1 Mongal and F1 jaguar). Treatments consisted of three organic fertilizer types (cow, chicken and goat dung) with a control without fertilizer. The dose of applied organic manure is 40t/ha (15kg/ridge). The treatments were randomly distributed into a complete randomized block design and replicated four times. The organic manure was dried and applied three week before transplanting. The results showed that the variety F1 Mongal is significantly (P <0.05) more productive (103kg/are ± 14.65kg/are) than the variety F1 jaguar (49kg/are ±13.22 kg/are). The study revealed that the droppings of chicken increased the forwardness of apparition of the floral buttons and the flowers of two (02) days compared to the witness. With regard to the height and the number of twining stems, they are significantly (P <0.05) increased with the application of chicken droppings (81,5cm ± 7.15cm and 85.5 ± 9.88cm) whereas the circumference to the collar of the tomato plants was significantly (p <0, 05) increased with the application of cow dungs (5.72cm ± 0.05cm). The best outputs (286.4kg/Are ±17.53kg/are) have been obtained with the chicken droppings. It is evident from this study that the combination of chicken droppings with the variety F1 Mongal is more productive than the variety F1 Jaguar with the same organic fertilizer in the municipality of Parakou.
